About the Scientific Calculator

This scientific calculator handles trigonometry, logarithms, exponents, roots, factorials and memory, applying proper operator precedence with brackets nested to any depth. The whole expression stays visible while you type, so a mistyped bracket can be corrected in place instead of starting the calculation again.

A scientific calculator covers what a basic one cannot: sine, cosine and tangent with their inverses, natural and base-10 logarithms, arbitrary powers and roots, factorials, and the constants pi and e.

Operator precedence is applied properly, so 2 + 3 × 4 gives 14 rather than 20, and brackets nest to any depth. The full expression stays on screen as you build it — the main practical advantage over a physical calculator, where one wrong key means starting again.

Degrees and radians are switchable, which matters because trigonometric answers are simply wrong in the other mode. Memory functions let you park an intermediate result rather than writing it down.

How to use the Scientific Calculator

  1. Set degrees or radians. Choose the angle mode before any trigonometry.
  2. Type your expression. Enter numbers, operators, functions and brackets. The expression stays visible.
  3. Evaluate. Get the result with operator precedence applied correctly.
  4. Store to memory. Keep an intermediate value for the next calculation.
